ATHENA provides a simple yet powerful way of documentaing your work. The project journal tool provides a blank text box in which you can write whatever you want. The text from this box is saved to the project file. When a project file is imported into ATHENA, any journal text will be restored to this text box.
This is a good way to document your progress through a data processing or analysis chore. It is also useful for documenting the nature of your samples in a way that stays with the data. Finally, it is a way to communicate with a collaborator or boss when exchanging data via a project file.
